If you put <INPUT type="text" title="Tooltiptext"></INPUT> into a text file, save the file as test.html and then open the test.html file with IE (I use 6), and then hover your mouse over the input box, the text "Tooltiptext" will appear, just like tooltips in other applications. I've also used it with the <TD> tag, although I'm pretty sure that it will work with most other things, which is why I was surprised it didn't work with <OPTION>.

Thanks. I'm happy enough to accept it's a limitation of IE, just as long I wasn't missing something obvious :). I was hoping to show a description of the item I was listing as I hovered over its name, while the ID is the value, like you suggested. Not a biggy, but would have been some nice functionality. Sometime, I'll have to see if it works in other browsers.

I was thinking there are Javascripts to generate a tooltip based on the onMouseOver event, but that doesn't seem to work with individual options either - at least not the scripts I've tried. Sorry.

I reckon the best you can hope for is a tooltip for the <select> itself, maybe containing all the option tips, but you're probably better just incorporating it into the text of each option. If you're still interested though, try this:
